sum 2 or 2 MGR CONJOINT FACIA AND WATER DAM The present invention relates to roof appurtenances and is more particularly concerned with conjoint facia and water dam means for a deck roof.

The practice of having a conjoint facia and water dam in association with a deck roof, the latter usually being flat or of substantially low pitch, is favored in the architectural and construction fields for such reasons as that the installation enables roof water to be suitably controlled without spilling over the brink of the deck and thence perhaps onto building side wall structure below the roof. A conjoint facia and water darn accordingly used may also serve as a barrier for other material on the roof deck such as gravel. Further beneficially, a conjoint facia and water darn as installed contributes facia which leads upwardly outside the end of a roof deck, coextends with the face of the roof deck end, and terminates upwardly of the deck. Roofing laid on the deck top surface is raised up at an end onto the inclined surface of a cant of the conjoint facia and water dam and flashing is added overlapping the roofing end on the cant and engaged with the facia above the cant. In

general, the flashing is for sealing against water penetration and the resulting barrier represented by the conjoint roof deck. facia and water dam, as installed, prevents water from spilling over the barrier, particularly when the deck roof is also equipped with one or more suitable water drains appropriately located entrantly behind the barrier.

An object of the present invention is the provision of a conjoint facia and water dam which is well suited for being produced commercially, may readily be installed, and is reliable in use having excellent thrust distribution within itself for maintaining stability and sealing off sheet roofing marginally outside a preceding portion of the sheet roofing which depends and closes off a gap to serve as a lower water barrier in advance of the seal.

Another object herein is to provide a conjoint facia and water dam of the character indicated wherein a free-ended resilient cant jaw, for supporting a marginal portion of sheet roofing, resiliently deflects in response to increase in thrust applied in establishing the aforementioned marginal seal and thereby stores energy for maintaining that seal this with allowing a preceding portion of the sheet roofing rearward of the seal to depend from the jaw and lead below a projecting end of the jaw.

Other objects of this invention in part will be obvious and in part pointed out more fully hereinafter.

In accordance with the present invention, a conjoint facia and water dam is had wherein facia means and cant means are interrelated with flashing and thrust means so that with the cant means secured disposed adjacent to an end of a roof deck, and with the facia means leading frontally outside the cant means and having a lower portion engaged for arresting upward movement of the facia means, the flashing and thrust means as provided and installed may act upon a marginal portion of sheet roofing for establishing and maintaining a seal with this portion upon the cant means while also introducing flashing from the seal to the facia means and thrust which is reactively transmitted to the facia means for stabilizing the facia means as a result of establishing the seal. The cant means comprises a resilient, free-ended cant jaw which leads upwardly behindthe facia means and thence has a rearwardly and downwardly inclined portion which carries a projecting end of the jaw located above the roof deck.

Upper facially, the rearwardly and downwardly inclined portion of the resilientjaw receives and supports the aforementioned marginal portion of the sheet roofing and is opposed by the flashing and thrust means which are adapted to exercise a clamping and sealing effect against the marginal portion of sheet roofing from above and incidentally thereto press the marginal portion of sheet roofing against the rearwardly and downwardly inclined portion of the resilient jaw, contribute flashing from the seal to the facia means while urging the resilient jaw to deflect outwardly and store energy resiliently and serving reactively to thrust the facia means upwardly and inwardly to establish stability. It will also be seen that the sheet roofing rearward of where clamped depends leading below the projecting end of the jaw, whereby the depending portion of the sheet material introduces a lower water barrier below the seal.

In the accompanying drawings wherein several embodiments of this invention are represented:

FIG. 1 is a broken away perspective view of a conjoint facia and water dam and of a roof deck having sheet roofing thereon with which the conjoint facia and water dam is associated;

FIG. 2 is a view companion to FIG. 1 but with portions omitted in order to show details relating to bracket structure and the cant means;

FIG. 3 is a vertical section relating to a conjoint facia and water dam similar to that in FIGS. 1 and 2 except for the bracket structure being modified; and

FIG. 4 is a vertical section of another modified form of the conjoint facia and water dam, notably having clip structure in the cant means and engaged with bracket structure.

In the embodiment represented in FIGS. 1 and 2 of the drawing, a conjoint facia and water darn, designated in general by reference numeral 10, is secured to roof deck 11 of a building, the deck comprising in the present instance a generally horizontal concrete slab 17, wooden 2 inch by 4 inch stringer means 13 securely held superimposed on the slab and forming an outside roof deck end 12 with the slab, the roof deck further including a bed 14 of roofing mixture filled in over the slab so as to be substantially level with the top of the aforementioned wooden stringer means and covered with roofing sheet material 15 including a top roofing sheet or flashing 16 such as of neoprene so as to have the latter be received and sealed in the conjoint facia and water dam 10 in a manner hereinafter to be described.

Having further reference now to the embodiment represented in FIGS. 1 and 2, the conjoint facia and water dam 10 includes a facia and heading and keeper member 18 which may for example be an extrusion or a product of rolling, made of aluminum alloy or from any other suitable material, and which member is characterized by including an upper facia wall and head portion 19, a first keeper component 20 and a second keeper component 21. The upper facia and head portion 19 is inclusive of an upper facia wall portion 224 of the facia wall 22, and a head wall component 23, which longitudinally and laterally border a recess 24, and the head wall component 23 leads laterally behind the upper facia wall portion. Furthermore, the upper facia and head portion 19 coextends longitudinally with the first and second keeper components and 21 which project laterally therefrom, the first keeper component 20 forming a bight with the head wall component 23, and the upper facia wall portion 22a and the end of the first keeper component 20 interposing a gap 26 giving access to the recess 24 so that the recess thence leading laterally communicates from above with a surface 200 of the first keeper component 20 in the recess. The second keeper component 21 is connected with the bight 25 and is outside the recess 24.

The foregoing arrangement is such that with the facia and heading and keeper member 18 situated in a given generally upright normal position of use as represented in FIG. 1, a lower facia wall portion 22b of the facia wall 22 leads outside the roof deck end 12 and upwardly of the roof deck to the upper facia wall portion 22a of the facia wall, placing the first and second keeper components 20 and 21 above the roof deck 11, with the recess 24 being upwardly entrant through gap 26 and thence widening laterally over surface 20a of the first keeper component. Also, in the present embodiment, the first and second keeper components 20 and 21, being integral with bight portion 25, project in generally opposite directions with reference to each other laterally with the end of the first keeper component 20 being in the gap 26 toward the facia wall 22. Head component 23 in the normal position of use leads laterally backwardly and at an acute angle downwardly with reference to upper facia wall portion 22a, and the second keeper component 21 leads laterally backwardly from bight portion 25 and forms an obtuse angle with the head component 23, while the first keeper component 20 projects generally horizontally forwardly toward the facia wall 22 from bight portion 25 and has surface 20a facing upwardly in the recess 24.

A cant member 30 of the conjoint roof deck facia and water dam 10 is disposed in a position adjacent to end 12 of the roof deck 11, as will be seen in FIG. 1, and is secured in that position to a series of angular brackets 50, the latter each having a first leg 51 and a second leg 52 which is substantially perpendicular to the first leg. The brackets 50 are for example made of aluminum alloy of any suitable grade and are spaced apart from one another such as by about 36 inches on centers, having the first legs 51 substantially horizontally disposed on the stringer means 13 of the roof deck and having the second legs 52 substantially vertically disposed. A pair of slots 51a in each of the first legs 51 lead having their direction of elongation be longitudinally of the first leg and receive headed fasteners 54 driven such as to allow the substantially vertical leg 52 of the related bracket to be brought approximately flush with the roof deck end 12 having the headed fasteners 54 only partially driven followed by fully driving these same fasteners for securing the bracket 50 to the roof deck.

The cant member 30 being of angular configuration in cross section and made of resilient material, such as galvanized 18 gauge sheet steel, has panels 31 and 32 which are delineated by parallel arrises 33, 34 and 35 leading longitudinally of the member. Panel 31, intermediately on the width thereof has slots 31c which lead substantially vertically in the direction of their elongation and are spaced apart from one another longitudinally of the panel so as to register with circular apertures 52a in the aforementioned second legs 52 of the brackets. Headed fasteners 57, such as self-tapping screws, enter the slots 31c and are driven up to engage the brackets 50 in bracket apertures 52a thus securing the cant member 30 to the brackets.

A plurality of cant members 30 may of course be made available as longitudinal sections which, in being installed with additional brackets 50 for extending the conjoint roof deck facia and water dam 10, are for example overlapped longitudinally or are longitudinally spliced through use ofa splice member of similar transverse configuration or are otherwise suitably jointed at adjacent longitudinal ends.

Panels 31 and 32 of the cant member 30 are angularly interrelated for panel 32 to lead rearwardly and downwardly inclined over the roof deck 11 while panel 31 engaged with the brackets 50 is substantially vertically disposed to have an upper portion 31a extending above the brackets to arris 34, and a lower portion 31b leading to arris 33 from which a forwardly and downwardly projecting tongue 36 of the cant member extends. Fromarris 35, the cant member 30 is provided with a projecting portion 37 terminally above the roof deck 11. It will accordingly be understood that the upper portion 31a of panel 31 constitutes a substantially vertical leg of a resilient, free-ended jaw which further comprises the rearwardly and downwardly inclined panel 32 and the projection 37, having the latter produce an end of the jaw.

The conjoint roofdeck facia and water dam 10 is also characterized by including flashing and thrust means wherein a flashing member 40 and a plurality of thrust screws are provided. The thrust screws 60 are disposed in a row and are threadedly engaged with the second keeper component 21 of the facia and heading and keeper member 18 at spaced apart locations longitudinally along the second keeper component so as to have the longitudinal axes of these screws intersect generally perpendicularly the rearwardly and downwardly inclined panel 32 of the cant member 30, this with having the shank ends of these same screws downward and the screw heads accordingly upward.

In flashing member 40, a bight wall portion 41 of back wall structure interconnects laterally opposite, longitudinally extending first and second wall and bearing components 42 and 43 of the flashing member. The second wall and bearing component 43 has a presser foot wall portion 43a outwardly of which integrally there is a lateral end flange 43b which projects downwardly spaced rearwardly of the cant member end or projection 37 when the first keeper component 20 of the facia and heading and keeper member 18 is engaged in the recess 24 at surface 200 by the first wall and bearing component 42. Meanwhile, a lower upwardly and rearwardly open hook extension 18a of the facia and heading and keeper member 18 is engaged with the downwardly and forwardly projecting tongue 36 of the cant member 30. Accordingly, the flashing member 40 leads out through gap 26, and the second wall and bearing component 43 covers marginal end portion 16a of sheet roofing 16 having the latter leading up upon the rearwardly and downwardly inclined panel 32 of the cant member 30 and beneath the presser foot wall portion 43a of the flashing member. This interrelation also establishes alignment of the thrust screws 60 longitudinally axially with the outer face ofthe presser foot wall portion 43a and by advancing the screws 60 into contact with the top face of the presser foot wall portion thrust is transmitted from the flashing member 40 to the sheet roofing 16 under the latter member and thence to the rearwardly and downwardly inclined panel 32 of the cant member, thereby causing the sheet roofing to be clamped and thus sealed to the flashing member 40. As an incident to receiving this thrust from screws 60, the resilient free-ended cant jaw, comprising the substantially upright panel portion 31a, the rearwardly and downwardly inclined panel 32, and projection 37, resiliently deflects having the panel portion 31a spring resiliently out toward or into abutment against the facia and heading and keeper member 18 as the rearwardly and downwardly inclined panel 32 is sprung resiliently down, thereby storing energy resiliently until stability is had. Counteractively, the screws 60 transmit upwardly and inwardly directed thrust to the facia and heading and keeper member 18 thus serving to urge the latter member upwardly against tongue 36 of the cant member 30 and inwardly toward the substantially upright panel portion 31a of the cant member 30, and thereby stabilize the assembly. In the particular installation represented in FIGS. 1 and 2, the sheet roofing 16 is carried over to terminate between upper portion 31a of panel 31 and the facia afforded by the facia and heading and keeper member 18 such as to have that terminal portion supplementally clamped thereby when the thrust screws 60 are set.

Flashing member 40 may illustratively be an extrusion, or a product of rolling or of sheet .bending, made of aluminum alloy or of any other suitable material. If desired, a plurality of these flashing members 40 may be jointed at longitudinal ends thereof such as by overlapping those ends, or through use of a splice plate of similar cross section. Where the joint is made overlapping beneath one or more of the thrust screws 60 on the length of the conjoint roof deckfacia and water dam 10, the directly related thrust screws are beneficial for compressionally securing the overlap or splice while exercising thrust upon the flashing for clamping the flashing to the sheet roofing. Joints between flashing members 40 may be concurrent with joints between facia and heading and keeper member 18 or may be staggered with reference to the latter jointsas occasion may demand. An example of structure whereby the conjoint roof deck facia and water dam is prolonged through the addition of a further facia and heading and keeper member 18 is indicated in FIGS. 1 and 2, wherein it will be seen that a liner and splice member 70 is installed to overlap the adjacent ends of the two members 18 and is configurated to conform substantially to the lateral inner facial contour of each facia and heading and keeper member starting with having a leg laterally facially abutting surface a of the first keeper component 20, in recess 24, and progressing to the bight of the lower hook wall extension 18a.

The sheet roofing l6 rearwardly of whereclamped depends below projection 37 of the cant member 30 such as to serve as intermediate flexible flashing, made for example of neoprene, between the main surface of the roof deck 11 and the flashing member 40 while thus introducing an abrupt water barrier below the latter member.

Further, in the present embodiment, an auxiliary cant 80 generally triangular in cross section and being for example made of wood is located rearwardly of the bracket legs 52 and resting upon bracket legs 51 and is firmly secured in that position in any suitable manner to the roof deck 11, thereby disposing a rearwardly and downwardly inclined surface 81 spaced downwardly from the projecting end 37 of the cant member 30. The sheet roofing 16 depending below the latter projecting end leads to the rearwardly and downwardly inclined surface 81 of the auxiliary cant 80 and thence is supported by that rearwardly and downwardly inclined surface down to the main surface of the roof deck 11. It will be understood that in certain embodiments still in accordance with the present invention the auxiliary cant 80 may be omitted.

In the embodiment represented in FIG. 3, modified substantially vertical legs 52' introduced in the brackets 50 are characterized by having a pair of laterally spaced apart channels longitudinally leading generally horizontally in a conjoint facia and water dam which for example otherwise is constructed as hereinbefore described with reference to the preceding embodiment. The opposed sidewalls in each of the channels are provided with ribs 71 for engaging the threads of screws 57 which are utilized through slots 31c in the cant member 30, as hereinbefore described, for securing the cant member to the brackets 50.

In FIG. 4, the embodiment therein represented associates resilient clip structure with brackets 50 which require no apertures or channels in their instead plain upright substantially vertical legs 52". A resilient clip leg 90, forming a component of the cant member 30", and accordingly having an extension secured to the underside of the rearwardly and downwardly inclined panel 32 coextends with the generally upwardly leading portion 31a" of panel 31" and forms therewith a downwardly open resilient clip receiving the upright legs 52" of brackets so as laterally resiliently to restrain the cant member 30 to the brackets. Apertures 91 in a lower portion of panel 31" receive headed fasteners 92 fully driven up to secure the cant member 30" to the roof deck end 12.

As the present invention lends itself to many possible embodiments and as many possible changes still in accordance with this invention may be made in the embodiments hereinbefore set forth, it will be distinctly understood that all matter described herein is to be interpreted as illustrative and not as a limitation.
